A
"surprise"
birthday
party
for
Jack
astounds
Will
when
his
estranged
older
brother
Sam
turns
up
at
the
fête
at
Grace's
invitation.
Not
only
do
sparks
fly
between
the
brothers,
but
electricity
of
a
different
sort
crackles
between
Grace
and
Sam.
Meanwhile,
Karen
flashes
her
platinum
card
for
Jack
as
the
pair
shop
until
they
drop
at
a
boutique
where
the
snooty
salesmen
previously
had
snubbed
Jack.
